  • app-server: Add an ability to watch events in the test client (#13080)
    Add a `watch` subcommand to `codex-app-server-test-client` binary to
    help in manual testing of events flow.
  • feat: include available decisions in command approval requests (#12758)
    Command-approval clients currently infer which choices to show from
    side-channel fields like `networkApprovalContext`,
    `proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
    the request shape harder to evolve, and it forces each client to
    replicate the server's heuristics instead of receiving the exact
    decision list for the prompt.
    
    This PR introduces a mapping between `CommandExecutionApprovalDecision`
    and `codex_protocol::protocol::ReviewDecision`:
    
    ```rust
    impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
        fn from(value: CoreReviewDecision) -> Self {
            match value {
                CoreReviewDecision::Approved => Self::Accept,
                CoreReviewDecision::ApprovedExecpolicyAmendment {
                    proposed_execpolicy_amendment,
                } => Self::AcceptWithExecpolicyAmendment {
                    execpolicy_amendment: proposed_execpolicy_amendment.into(),
                },
                CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
                CoreReviewDecision::NetworkPolicyAmendment {
                    network_policy_amendment,
                } => Self::ApplyNetworkPolicyAmendment {
                    network_policy_amendment: network_policy_amendment.into(),
                },
                CoreReviewDecision::Abort => Self::Cancel,
                CoreReviewDecision::Denied => Self::Decline,
            }
        }
    }
    ```
    
    And updates `CommandExecutionRequestApprovalParams` to have a new field:
    
    ```rust
    available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
    ```
    
    when, if specified, should make it easier for clients to display an
    appropriate list of options in the UI.
    
    This makes it possible for `CoreShellActionProvider::prompt()` in
    `unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
    adding support for `ApprovedForSession` when approving a skill script,
    which was previously missing in the TUI.
    
    Note this results in a significant change to `exec_options()` in
    `approval_overlay.rs`, as the displayed options are now derived from
    `available_decisions: &[ReviewDecision]`.
    
    ## What Changed
    
    - Add `available_decisions` to
    [`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
    including helpers to derive the legacy default choices when older
    senders omit the field.
    - Map `codex_protocol::protocol::ReviewDecision` to app-server
    `CommandExecutionApprovalDecision` and expose the ordered list as
    experimental `availableDecisions` in
    [`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
    - Thread optional `available_decisions` through the core approval path
    so Unix shell escalation can explicitly request `ApprovedForSession` for
    session-scoped approvals instead of relying on client heuristics.
    [`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
    - Update the TUI approval overlay to build its buttons from the ordered
    decision list, while preserving the legacy fallback when
    `available_decisions` is missing.
    - Update the app-server README, test client output, and generated schema
    artifacts to document and surface the new field.
    
    ## Testing
    
    - Add `approval_overlay.rs` coverage for explicit decision lists,
    including the generic `ApprovedForSession` path and network approval
    options.
    - Update `chatwidget/tests.rs` and app-server protocol tests to populate
    the new optional field and keep older event shapes working.
    
    ## Developers Docs
    
    - If we document `item/commandExecution/requestApproval` on
    [developers.openai.com/codex](https://developers.openai.com/codex), add
    experimental `availableDecisions` as the preferred source of approval
    choices and note that older servers may omit it.
  • Revert "Add skill approval event/response (#12633)" (#12811)
    This reverts commit https://github.com/openai/codex/pull/12633. We no
    longer need this PR, because we favor sending normal exec command
    approval server request with `additional_permissions` of skill
    permissions instead
  • feat: add search term to thread list (#12578)
    Add `searchTerm` to `thread/list` that will search for a match in the
    titles (the condition being `searchTerm` $$\in$$ `title`)
  • feat(ui): add network approval persistence plumbing (#12358)
    ## Summary
    - add TUI approval options for persistent network host rules
    - add app-server v2 approval payload plumbing for network approval
    context + proposed network policy amendments
    - add app-server handling to translate `applyNetworkPolicyAmendment`
    decisions back into core review decisions
    - update docs/test client output and generated app-server schemas/types
  • feat: add experimental additionalPermissions to v2 command execution approval requests (#12737)
    This adds additionalPermissions to the app-server v2
    item/commandExecution/requestApproval payload as an experimental field.
    
    The field is now exposed on CommandExecutionRequestApprovalParams and is
    populated from the existing core approval event when a command requests
    additional sandbox permissions.
    
    This PR also contains changes to make server requests to support
    experiment API.

  • Add skill approval event/response (#12633)
    Set the stage for skill-level permission approval in addition to
    command-level.
    
    Behind a feature flag.
  • Refactor network approvals to host/protocol/port scope (#12140)
    ## Summary
    Simplify network approvals by removing per-attempt proxy correlation and
    moving to session-level approval dedupe keyed by (host, protocol, port).
    Instead of encoding attempt IDs into proxy credentials/URLs, we now
    treat approvals as a destination policy decision.
    
    - Concurrent calls to the same destination share one approval prompt.
    - Different destinations (or same host on different ports) get separate
    prompts.
    - Allow once approves the current queued request group only.
    - Allow for session caches that (host, protocol, port) and auto-allows
    future matching requests.
    - Never policy continues to deny without prompting.
    
    Example:
    - 3 calls: 
      - a.com (line 443)
      - b.com (line 443)
      - a.com (line 443)
    => 2 prompts total (a, b), second a waits on the first decision.
    - a.com:80 is treated separately from a.com line 443
    
    ## Testing
    - `just fmt` (in `codex-rs`)
    - `cargo test -p codex-core tools::network_approval::tests`
    - `cargo test -p codex-core` (unit tests pass; existing
    integration-suite failures remain in this environment)
  • feat(core): zsh exec bridge (#12052)
    zsh fork PR stack:
    - https://github.com/openai/codex/pull/12051 
    - https://github.com/openai/codex/pull/12052 👈 
    
    ### Summary
    This PR introduces a feature-gated native shell runtime path that routes
    shell execution through a patched zsh exec bridge, removing MCP-specific
    behavior from the shell hot path while preserving existing
    CommandExecution lifecycle semantics.
    
    When shell_zsh_fork is enabled, shell commands run via patched zsh with
    per-`execve` interception through EXEC_WRAPPER. Core receives wrapper
    IPC requests over a Unix socket, applies existing approval policy, and
    returns allow/deny before the subcommand executes.
    
    ### What’s included
    **1) New zsh exec bridge runtime in core**
    - Wrapper-mode entrypoint (maybe_run_zsh_exec_wrapper_mode) for
    EXEC_WRAPPER invocations.
    - Per-execution Unix-socket IPC handling for wrapper requests/responses.
    - Approval callback integration using existing core approval
    orchestration.
    - Streaming stdout/stderr deltas to existing command output event
    pipeline.
    - Error handling for malformed IPC, denial/abort, and execution
    failures.
    
    **2) Session lifecycle integration**
    SessionServices now owns a `ZshExecBridge`.
    Session startup initializes bridge state; shutdown tears it down
    cleanly.
    
    **3) Shell runtime routing (feature-gated)**
    When `shell_zsh_fork` is enabled:
    - Build execution env/spec as usual.
    - Add wrapper socket env wiring.
    - Execute via `zsh_exec_bridge.execute_shell_request(...)` instead of
    the regular shell path.
    - Non-zsh-fork behavior remains unchanged.
    
    **4) Config + feature wiring**
    - Added `Feature::ShellZshFork` (under development).
    - Added config support for `zsh_path` (optional absolute path to patched
    zsh):
    - `Config`, `ConfigToml`, `ConfigProfile`, overrides, and schema.
    - Session startup validates that `zsh_path` exists/usable when zsh-fork
    is enabled.
    - Added startup test for missing `zsh_path` failure mode.
    
    **5) Seatbelt/sandbox updates for wrapper IPC**
    - Extended seatbelt policy generation to optionally allow outbound
    connection to explicitly permitted Unix sockets.
    - Wired sandboxing path to pass wrapper socket path through to seatbelt
    policy generation.
    - Added/updated seatbelt tests for explicit socket allow rule and
    argument emission.
    
    **6) Runtime entrypoint hooks**
    - This allows the same binary to act as the zsh wrapper subprocess when
    invoked via `EXEC_WRAPPER`.
    
    **7) Tool selection behavior**
    - ToolsConfig now prefers ShellCommand type when shell_zsh_fork is
    enabled.
    - Added test coverage for precedence with unified-exec enabled.
  • feat(core): plumb distinct approval ids for command approvals (#12051)
    zsh fork PR stack:
    - https://github.com/openai/codex/pull/12051 👈 
    - https://github.com/openai/codex/pull/12052
    
    With upcoming support for a fork of zsh that allows us to intercept
    `execve` and run execpolicy checks for each subcommand as part of a
    `CommandExecution`, it will be possible for there to be multiple
    approval requests for a shell command like `/path/to/zsh -lc 'git status
    && rg \"TODO\" src && make test'`.
    
    To support that, this PR introduces a new `approval_id` field across
    core, protocol, and app-server so that we can associate approvals
    properly for subcommands.

  • feat: make sandbox read access configurable with ReadOnlyAccess (#11387)
    `SandboxPolicy::ReadOnly` previously implied broad read access and could
    not express a narrower read surface.
    This change introduces an explicit read-access model so we can support
    user-configurable read restrictions in follow-up work, while preserving
    current behavior today.
    
    It also ensures unsupported backends fail closed for restricted-read
    policies instead of silently granting broader access than intended.
    
    ## What
    
    - Added `ReadOnlyAccess` in protocol with:
      - `Restricted { include_platform_defaults, readable_roots }`
      - `FullAccess`
    - Updated `SandboxPolicy` to carry read-access configuration:
      - `ReadOnly { access: ReadOnlyAccess }`
      - `WorkspaceWrite { ..., read_only_access: ReadOnlyAccess }`
    - Preserved existing behavior by defaulting current construction paths
    to `ReadOnlyAccess::FullAccess`.
    - Threaded the new fields through sandbox policy consumers and call
    sites across `core`, `tui`, `linux-sandbox`, `windows-sandbox`, and
    related tests.
    - Updated Seatbelt policy generation to honor restricted read roots by
    emitting scoped read rules when full read access is not granted.
    - Added fail-closed behavior on Linux and Windows backends when
    restricted read access is requested but not yet implemented there
    (`UnsupportedOperation`).
    - Regenerated app-server protocol schema and TypeScript artifacts,
    including `ReadOnlyAccess`.
    
    ## Compatibility / rollout
    
    - Runtime behavior remains unchanged by default (`FullAccess`).
    - API/schema changes are in place so future config wiring can enable
    restricted read access without another policy-shape migration.
  • chore: persist turn_id in rollout session and make turn_id uuid based (#11246)
    Problem:
    1. turn id is constructed in-memory;
    2. on resuming threads, turn_id might not be unique;
    3. client cannot no the boundary of a turn from rollout files easily.
    
    This PR does three things:
    1. persist `task_started` and `task_complete` events;
    1. persist `turn_id` in rollout turn events;
    5. generate turn_id as unique uuids instead of incrementing it in
    memory.
    
    This helps us resolve the issue of clients wanting to have unique turn
    ids for resuming a thread, and knowing the boundry of each turn in
    rollout files.
    
    example debug logs
    ```

Ready for the next change in `codex-rs`; I can continue from the current in-progress diff or start a new task." }], status: Completed, error: None }

Send the specific change you want in `codex-rs`, and I’ll implement it and run the required checks." }], status: Completed, error: None }
    ```
    
    backward compatibility:
    if you try to resume an old session without task_started and
    task_complete event populated, the following happens:
    - If you resume and do nothing: those reconstructed historical IDs can
    differ next time you resume.
    - If you resume and send a new turn: the new turn gets a fresh UUID from
    live submission flow and is persisted, so that new turn’s ID is stable
    on later resumes.
    I think this behavior is fine, because we only care about deterministic
    turn id once a turn is triggered.

  • feat: experimental flags (#10231)
    ## Problem being solved
    - We need a single, reliable way to mark app-server API surface as
    experimental so that:
      1. the runtime can reject experimental usage unless the client opts in
    2. generated TS/JSON schemas can exclude experimental methods/fields for
    stable clients.
    
    Right now that’s easy to drift or miss when done ad-hoc.
    
    ## How to declare experimental methods and fields
    - **Experimental method**: add `#[experimental("method/name")]` to the
    `ClientRequest` variant in `client_request_definitions!`.
    - **Experimental field**: on the params struct, derive `ExperimentalApi`
    and annotate the field with `#[experimental("method/name.field")]` + set
    `inspect_params: true` for the method variant so
    `ClientRequest::experimental_reason()` inspects params for experimental
    fields.
    
    ## How the macro solves it
    - The new derive macro lives in
    `codex-rs/codex-experimental-api-macros/src/lib.rs` and is used via
    `#[derive(ExperimentalApi)]` plus `#[experimental("reason")]`
    attributes.
    - **Structs**:
    - Generates `ExperimentalApi::experimental_reason(&self)` that checks
    only annotated fields.
      - The “presence” check is type-aware:
        - `Option<T>`: `is_some_and(...)` recursively checks inner.
        - `Vec`/`HashMap`/`BTreeMap`: must be non-empty.
        - `bool`: must be `true`.
        - Other types: considered present (returns `true`).
    - Registers each experimental field in an `inventory` with `(type_name,
    serialized field name, reason)` and exposes `EXPERIMENTAL_FIELDS` for
    that type. Field names are converted from `snake_case` to `camelCase`
    for schema/TS filtering.
    - **Enums**:
    - Generates an exhaustive `match` returning `Some(reason)` for annotated
    variants and `None` otherwise (no wildcard arm).
    - **Wiring**:
    - Runtime gating uses `ExperimentalApi::experimental_reason()` in
    `codex-rs/app-server/src/message_processor.rs` to reject requests unless
    `InitializeParams.capabilities.experimental_api == true`.
    - Schema/TS export filters use the inventory list and
    `EXPERIMENTAL_CLIENT_METHODS` from `client_request_definitions!` to
    strip experimental methods/fields when `experimental_api` is false.
  • Chore: add cmd related info to exec approval request (#9659)
    ### Summary
    We now rely purely on `item/commandExecution/requestApproval` item to
    render pending approval in VSCE and app. With v2 approach, it does not
    include the actual cmd that it is attempting and therefore we can only
    use `proposedExecpolicyAmendment` to render which can be incomplete.
    
    ### Reproduce
    * Add `prefix_rule(pattern=["echo"], decision="prompt")` to your
    `~/.codex/rules.default.rules`.
    * Ask to `Run  echo "approval-test" please` in VSCE or app. 
    * The pending approval protal does show up but with no content

    #### Sample output

        "threadId":"019be439-5a90-7600-a7ea-2d2dcc50302a",
        "turnId":"0",
        "itemId":"call_usgnQ4qEX5U9roNdjT7fPzhb",
        "reason":"`/bin/zsh -lc 'echo \"testing\"'` requires approval by policy",
        "proposedExecpolicyAmendment":null
      }}
    
    ```
    
    ### Fix
    Inlude `command` string, `cwd` and `command_actions` in
    `CommandExecutionRequestApprovalParams` so that consumers can display
    the correct command instead of relying on exec policy output.
  • Persist text elements through TUI input and history (#9393)
    Continuation of breaking up this PR
    https://github.com/openai/codex/pull/9116
    
    ## Summary
    - Thread user text element ranges through TUI/TUI2 input, submission,
    queueing, and history so placeholders survive resume/edit flows.
    - Preserve local image attachments alongside text elements and rehydrate
    placeholders when restoring drafts.
    - Keep model-facing content shapes clean by attaching UI metadata only
    to user input/events (no API content changes).
    
    ## Key Changes
    - TUI/TUI2 composer now captures text element ranges, trims them with
    text edits, and restores them when submission is suppressed.
    - User history cells render styled spans for text elements and keep
    local image paths for future rehydration.
    - Initial chat widget bootstraps accept empty `initial_text_elements` to
    keep initialization uniform.
    - Protocol/core helpers updated to tolerate the new InputText field
    shape without changing payloads sent to the API.
  • Add text element metadata to protocol, app server, and core (#9331)
    The second part of breaking up PR
    https://github.com/openai/codex/pull/9116
    
    Summary:
    
    - Add `TextElement` / `ByteRange` to protocol user inputs and user
    message events with defaults.
    - Thread `text_elements` through app-server v1/v2 request handling and
    history rebuild.
    - Preserve UI metadata only in user input/events (not `ContentItem`)
    while keeping local image attachments in user events for rehydration.
    
    Details:
    
    - Protocol: `UserInput::Text` carries `text_elements`;
    `UserMessageEvent` carries `text_elements` + `local_images`.
    Serialization includes empty vectors for backward compatibility.
    - app-server-protocol: v1 defines `V1TextElement` / `V1ByteRange` in
    camelCase with conversions; v2 uses its own camelCase wrapper.
    - app-server: v1/v2 input mapping includes `text_elements`; thread
    history rebuilds include them.
    - Core: user event emission preserves UI metadata while model history
    stays clean; history replay round-trips the metadata.

  • fix: implement 'Allow this session' for apply_patch approvals (#8451)
    **Summary**
    This PR makes “ApprovalDecision::AcceptForSession / don’t ask again this
    session” actually work for `apply_patch` approvals by caching approvals
    based on absolute file paths in codex-core, properly wiring it through
    app-server v2, and exposing the choice in both TUI and TUI2.
    - This brings `apply_patch` calls to be at feature-parity with general
    shell commands, which also have a "Yes, and don't ask again" option.
    - This also fixes VSCE's "Allow this session" button to actually work.
    
    While we're at it, also split the app-server v2 protocol's
    `ApprovalDecision` enum so execpolicy amendments are only available for
    command execution approvals.
    
    **Key changes**
    - Core: per-session patch approval allowlist keyed by absolute file
    paths
    - Handles multi-file patches and renames/moves by recording both source
    and destination paths for `Update { move_path: Some(...) }`.
    - Extend the `Approvable` trait and `ApplyPatchRuntime` to work with
    multiple keys, because an `apply_patch` tool call can modify multiple
    files. For a request to be auto-approved, we will need to check that all
    file paths have been approved previously.
    - App-server v2: honor AcceptForSession for file changes
    - File-change approval responses now map AcceptForSession to
    ReviewDecision::ApprovedForSession (no longer downgraded to plain
    Approved).
    - Replace `ApprovalDecision` with two enums:
    `CommandExecutionApprovalDecision` and `FileChangeApprovalDecision`
    - TUI / TUI2: expose “don’t ask again for these files this session”
    - Patch approval overlays now include a third option (“Yes, and don’t
    ask again for these files this session (s)”).
        - Snapshot updates for the approval modal.
    
    **Tests added/updated**
    - Core:
    - Integration test that proves ApprovedForSession on a patch skips the
    next patch prompt for the same file
    - App-server:
    - v2 integration test verifying
    FileChangeApprovalDecision::AcceptForSession works properly
    
    **User-visible behavior**
    - When the user approves a patch “for session”, future patches touching
    only those previously approved file(s) will no longer prompt gain during
    that session (both via app-server v2 and TUI/TUI2).
    
    **Manual testing**
    Tested both TUI and TUI2 - see screenshots below.

  • fix: remove serde(flatten) annotation for TurnError (#7499)
    The problem with using `serde(flatten)` on Turn status is that it
    conditionally serializes the `error` field, which is not the pattern we
    want in API v2 where all fields on an object should always be returned.
    
    ```
    #[derive(Serialize, Deserialize, Debug, Clone, PartialEq, JsonSchema, TS)]
    #[serde(rename_all = "camelCase")]
    #[ts(export_to = "v2/")]
    pub struct Turn {
        pub id: String,
        /// Only populated on a `thread/resume` response.
        /// For all other responses and notifications returning a Turn,
        /// the items field will be an empty list.
        pub items: Vec<ThreadItem>,
        #[serde(flatten)]
        pub status: TurnStatus,
    }
    
    #[derive(Serialize, Deserialize, Debug, Clone, PartialEq, JsonSchema, TS)]
    #[serde(tag = "status", rename_all = "camelCase")]
    #[ts(tag = "status", export_to = "v2/")]
    pub enum TurnStatus {
        Completed,
        Interrupted,
        Failed { error: TurnError },
        InProgress,
    }
    ```
    
    serializes to:
    ```
    {
      "id": "turn-123",
      "items": [],
      "status": "completed"
    }
    
    {
      "id": "turn-123",
      "items": [],
      "status": "failed",
      "error": {
        "message": "Tool timeout",
        "codexErrorInfo": null
      }
    }
    ```
    
    Instead we want:
    ```
    {
      "id": "turn-123",
      "items": [],
      "status": "completed",
      "error": null
    }
    
    {

  • [app-server] feat: v2 apply_patch approval flow (#6760)
    This PR adds the API V2 version of the apply_patch approval flow, which
    centers around `ThreadItem::FileChange`.
    
    This PR wires the new RPC (`item/fileChange/requestApproval`, V2 only)
    and related events (`item/started`, `item/completed` for
    `ThreadItem::FileChange`, which are emitted in both V1 and V2) through
    the app-server
    protocol. The new approval RPC is only sent when the user initiates a
    turn with the new `turn/start` API so we don't break backwards
    compatibility with VSCE.
    
    Similar to https://github.com/openai/codex/pull/6758, the approach I
    took was to make as few changes to the Codex core as possible,
    leveraging existing `EventMsg` core events, and translating those in
    app-server. I did have to add a few additional fields to
    `EventMsg::PatchApplyBegin` and `EventMsg::PatchApplyEnd`, but those
    were fairly lightweight.
    
    However, the `EventMsg`s emitted by core are the following:
    ```
    1) Auto-approved (no request for approval)

    - EventMsg::PatchApplyBegin
    - EventMsg::PatchApplyEnd
    
    2) Approved by user
    - EventMsg::ApplyPatchApprovalRequest
    - EventMsg::PatchApplyBegin
    - EventMsg::PatchApplyEnd
    
    3) Declined by user
    - EventMsg::ApplyPatchApprovalRequest
    - EventMsg::PatchApplyBegin
    - EventMsg::PatchApplyEnd
    ```
    
    For a request triggering an approval, this would result in:
    ```
    item/fileChange/requestApproval
    item/started
    item/completed
    ```
    
    which is different from the `ThreadItem::CommandExecution` flow
    introduced in https://github.com/openai/codex/pull/6758, which does the
    below and is preferable:
    ```
    item/started
    item/commandExecution/requestApproval
    item/completed
    ```
    
    To fix this, we leverage `TurnSummaryStore` on codex_message_processor
    to store a little bit of state, allowing us to fire `item/started` and
    `item/fileChange/requestApproval` whenever we receive the underlying
    `EventMsg::ApplyPatchApprovalRequest`, and no-oping when we receive the
    `EventMsg::PatchApplyBegin` later.
    
    This is much less invasive than modifying the order of EventMsg within
    core (I tried).
    
    The resulting payloads:

  • [app-server] introduce turn/completed v2 event (#6800)
    similar to logic in

    this PR also makes `items` field in `Turn` optional. For now, we only
    populate it when we resume a thread, and leave it as None for all other
    places until we properly rewrite core to keep track of items.
